This dairy-free oat milk smoothie is a healthy, refreshing drink full of fruit flavor. Oat milk is the perfect base for a thick, delicious vegan drink.

Oat milk is ideal for a smoothie because it’s naturally thick. It can be used in just about any smoothie recipe for a smooth, creamy drink. It’s also one of the most affordable non-dairy milks, with homemade oat milk costing just $.07 per cup.

This oat milk smoothie has a vibrant berry flavor, and the oat milk gives it a great texture. The banana sweetens the smoothie, and you can add a little pure maple syrup if you want it even sweeter.

I like to portion this smoothie into one cup servings, but you can make bigger or smaller servings depending on your smoothie appetite. This recipe yields four cups. Try it as a snack or alongside a meal for a quick burst of nutrients.

Oat Milk Smoothie Step-By-Step Instructions

Ingredients in bowls

Step One: Gather the ingredients

Gather the four ingredients for this recipe: oat milk, banana, frozen mixed berries, and pure maple syrup.

Step Two: Add the ingredients in the order listed

As with most blender recipes, it’s important to add the liquid to the blender first. This will allow the blades of the blender to work properly and puree the solid ingredients into a smooth drink.

Step Three: Blend the smoothie

Starting at low speed and gradually increasing to high speed, process the mixture until smooth. This will take about 30 seconds. Taste the smoothie, and add the pure maple syrup if you think it needs it (sometimes the natural sweetness of the banana is enough). Pour the smoothie into four glasses and serve.

Tips and Frequently Asked Questions

What variations can be made in this oat milk smoothie?

You can add a bit of peanut butter, almond butter, or another nut butter for extra protein and a creamy texture. Other frozen fruit such as pineapple, mango, or peach can be added, and you can switch out other berries for the strawberries, raspberries, and blueberries.

Does the fruit need to be frozen?

I recommend using frozen berries in this oat milk smoothie. They help thicken the drink and keep it cold. If you’d prefer to use fresh berries, you can add a couple ice cubes and a bit of extra fruit to get the best texture. You can use either fresh or frozen banana. And for an even thicker consistency in your smoothie, use a little less milk.

Can other plant-based milk be substituted?

Yes, this recipe works well with just about any milk, including almond milk, coconut milk, and soy milk.

Can this recipe be made ahead of time?

If you don’t drink the whole batch right away, the excess can be stored in the refrigerator for a few days. It does taste best immediately after blending.

Can I use store-bought oat milk?

Yes, store-bought oat milk works well in this recipe. But for the most affordable smoothie, you can make your own homemade oat milk before proceeding with this smoothie recipe. The extra milk can be used in cereal, baking recipes, or just about anywhere else you would use milk. Store it in the refrigerator until ready to use.

Try oat milk in a tropical green smoothie, apple smoothie, pomegranate smoothie, or chocolate oat milk for a delicious snack.
